Title of the thesis:Self-commissioning speed servo drive with induction motor
Summary:Thesis focuses on the design and verification of advanced control methods of induction motors, using the principles of adaptation and self-commissioning on the basis of continuous parameter identification. The main objective of the thesis was focused on the design of new techniques for self-commissioning of the converter parameters for sensorless vector control. This objective consisted of a theoretical analysis of the problem, which lied both in the design of modern methods of identification as well as the design of self-tuning control algorithms, using the results of the on-line identification. Theoretical knowledge of self-tuning controller algorithm design was effectively transferred into practical algorithms written in C programming language; it is now practically usable for a very wide range of speed and is successfully used in the frequency converter VONSCH UNIFREM 400 as part of the basic firmware since the version 2.020. Based on the proposed methods of vector control, performance analysis and experimental results; high quality and effectiveness of the proposed methods and algorithms for induction motor control can be reported.
Key words:self-commissioning, vector control, induction motor, Luenberger observer, stabilization, on-line identification
